I have used both the ls800 from motion and Samsung q1 Ultra Prem outdoors in direct sunlight. The Q1 Ultra Prem is a bit easier to see out of doors. The Q1 has not compromised to have a smaller Higher resolution screen, battery life has been 5 1/2 hours to 7 hours. The size has been very nice. Seems like a pretty good option now that the ls800 form factor got larger.
